Subject: [PATCH net-next v2 0/2] net: ethernet: ti: am65-cpsw: Fix MAC address fetching
Date: Mon, 14 Apr 2025 10:43:34 +0200 [thread overview]
Message-ID: <20250414084336.4017237-1-mwalle@kernel.org> (raw)
MAC addresses can be fetched from a NVMEM device. of_get_mac_address()
will return EPROBE_DEFER if that device is not available yet. That
isn't handled correctly by the driver and it will always fall back
to either a random MAC address or it's own "fetch by fuse" method.
Also, if the ethernet (sub)node has a link to the nvmem device,
it will fail to create a device link as the fwnode parameter isn't
populated. That's fixed in the first patch.
Michael Walle (2):
net: ethernet: ti: am65-cpsw: set fwnode for ports
net: ethernet: ti: am65-cpsw: handle -EPROBE_DEFER
